IEDWARD SONNTAG, OF CHICAGO, ILLINOIS, fASSIGNOR TO DAVID B. JOHNSON, OF CHICAGO, ILLINOIS.

COMBINED WEATHER-STRIP AND WINDOW- SUPPORTER.

Specification of Letters'. Patent.

'BatentedgDed 15, 1914.

The essential object of the invention is to-` provide a device which provides both a water-tight joint for the sash and which holds the sash firm so as to prevent rattling and vibrating thereof.

As will be evident by an inspection of my prior United States Patent No. 854,544,

granted July 2, 1907, the herein-described invention embodies certain improvements over my own prior device.

In the drawin s, Figure 1 is a vertical sectional view t rough a window frame showing the sashes in the position normally assumed by them when both sashes are closed; Fig. 2 is a transverse sectional view taken through both of the sashes; Fig. 3 is a perspective view of that form of the invention which is adapted to be placed between the frames and the stiles lor rails of the sashes; and Fig. 4 is a view of that form of the invention adapted to be placed between the top rail of one sash and the bott0m rail of the other sash.

The frames 1 are of ordinary construction and are provided with the usual stops 2, 3, and 4, which stops form the grooves within which the sashes areadapted to slide. The sashes themselves are preferably rectangular in shape, being provided with the usual Stiles 5 and rails 6 within which the panes of glass 7 are suitably mounted. Rigidly secured in any manner to the frame are the weather strips 4.

Each of the weather strips 4 is formed of a piece of sheet metal or other similar material preferably formed with three arms 9, 10, and 11, and one of these arms is bent double upon itself as indicated at 12. From said portion 12 a spring-like leaf 13 extends. The arm 9 is provided with a bead 14 and the leaf 13 with a bead 15.

The weather strip is applied to the frame as best shown in Figs. 1 and 2, from which figures it will be seen that the arm 9 lrests against the side frame 1, whereas the arms 10 and 11 fit against the stops 3 or 4, the device being preferably held in place by nails or screws 17 which pass through perforations 16 in the members ll-fand 12. The

. beads' 14 will press against those surfaces of the stiles 5 which are nearest the frame 1, and the beaded leaf spring 13 will press against the surface of the stiles 5 nearest the stops 3 and 4.

- As will be obvious from inspection of the drawings, the members 9 and 11 are parallel to each other and are both at right angles to the member 10. The leaf spring 13 issubstantially parallel to the member 10 but the position assumed by the leaf spring will Vary somewhat according to the thickness 'o the Stiles and rails.

The leaf spring-like member 13 is connected tothe arm 12 by a web 19 which extends at an angle of approximately 45 degrecs to both the leaf spring 13 and the arm 12, and the acute angle 20 at which the leaf spring 13 and the web 19 are joined extends outwardly Ipointing away from the arm 9.

At the top of Fig. 1 the weather strip is shown as being applied to a window frame so as to engage the cross rail 6. When the right-hand sash in said figure is pulled down, the rail 6 will ride clear of the weather strip but when the sash is moved to the position depicted in said figure the strip wlll engage the rail 6 and will hold the window tight.

In Fig. 4 a modified device is shown, which modification is intended to be applied in the positions shown at the center and at the bottom of Fig. 1. In this modification the arm 2l is provided with a flange 22, and screws 23, which pass through erforations 24, hold the weather strip secure y upon one of the rails. The leaf spring 25 is secured directly to the arm 20, and the connecting web 19 of the other form of the invention is omitted. That form of the invention depicted in Fig. 4 is especially adapted for making a tight joint between two rails or between the rail and the bottom member of the frame, for at the sill there is usually not enough room to use the form of the invention shown in Fig. 3.

It is obvious that when a sash is used in connection with the herein described invention,- the sash will be held firmly in place so that rattling is prevented and the different joints securely closed against drafts; and it is further obvious that many details of construction may be varied without departing from the scope of the invention.

I claim as invention: l 4 A Weather strip comprising a leaf engaging the stop and lying 1n a plane parallel to the ,surface of the ane, a second leaf at 5 right angles to said' rst-mentioned leaf and adapted to en age the rail o r stile of the sash, a third eaf engaging the stop, said,

third-mentionedleaf bemg parallel to said second-mentioned leaf, but on that side of. 10 .the stop opposite the second-mentioned leaf,

anclav fourth leaf substantially parallel t0 said first-mentioned leaf and in spring-like connection with said third-mentioned leaf.

In testimony whereof I hereunto aix my signature inthe presence of two Witnesses.
